The document provides an overview of the digestive system, with sections focused on specific organs including the colon, esophagus, oral cavity, and stomach. Key points include:
- The colon removes water and nutrients from waste and contains the cecum, ascending colon, transverse colon, descending colon, and sigmoid colon.
- The esophagus transports food from the mouth to the stomach through peristalsis. It contains striated muscle and sphincters to control food movement.
- The oral cavity includes the cheeks, gums, tongue, palate, and uvula. The tongue contains taste buds and the mouth is used to break down food with teeth and saliva.

ANATOMY, FUNCTIONS AND SECRETIONS
Anatomically, the stomach is usually divided in to two major parts:
1. Body 2. Antrum
Physiologically, the stomach is divided in to
1. the “ ORAD” portion, comprises of about first two thirds of the body.
2. the “CAUDAD” portion, comprises the remainder of the body plus the antrum.
The esophagus empties into the orad stomach.
primary function is to store food.
800 -1500 mL of food. Or 0.8 – 1.5 L
Little mixing occurs in the orad stomach because the contractions are weak and infrequent, so the ingested food remains in unmixed.
vagovagal reflex :
“initiated by swallowing or distention is define as,” A reflex that occurs from the stomach to the brain stem and then back to the stomach reduces the tone in the muscular wall of the body of the stomach so that the wall bulges progressively outward, accommodating greater and greater quantities of food up to a limit in the completely relaxed stomach”.

Solution
I.Mouth:
It is the first organ of the digestive system and food is first taken into the body via the mouth. It
consists of tongue, teeth and saliva. These three elements work together to aid the procedure of
swallowing. Teeth are used for the process of mastication to make the food smaller is size which
is softened by the saliva and turned into bolus by the tongue for aiding the process of
swallowing. Saliva is used for softening the food and digesting starch by the salivary amylase.
Swallowing occurs bytwo involuntary actions - the soft palate, the back of the roof of the mouth,
closes off the nasal cavity, and the epiglottis, a flap of cartilage, tilts downwards to seal the
trachea.
II.II. Oesophagus – the food passes through the throat and enters the food pipe or trachea. The
walls of the oesophagus are muscular and elastic and helps propel the food towards the stomach
by rhythmic muscular contractions called peristalsis. Just before the opening to the stomach is an
important ring-shaped muscle called the lower esophageal sphincter (LES). This sphincter opens
to let food pass into the stomach and closes to keep it there. LES prevents regurgitation.
III.Stomach – the food is propelled into the stomach where it stays for upto five hours. The food
along with the gastric juices of the stomach is converted to chyme by the churning action of the
stomach walls. The stomach walls secrete strong acid (HCl) to make the food acidic in order for
the enzyme pepsin to work. Pepsin is important for the breakdown of proteins. Once the contents
of the stomach are properly processed they are released into the upper small intestine through the
pyloric sphincter.
IV.Small intestine – Small intestine is the longest organ of the digestive system and its composed
of three segments called the Duodenum, Jejunum and ileum. The food is released into the
duodenum from the pyloric sphincter where the pancreatic juices are released along with bile
juice from the bile duct. The bile turns the food alkaline so that the pancreatic enzymes can
process the food. These enzymes require a alkaline medium to digest the fats and lipids. Contents
of the small intestine start out semi-solid, and end in a liquid form after passing through the
organ. Water, bile, enzymes, and mucous contribute to the change in consistency. The duodenum
is largely responsible for the continuous breaking-down process, with the jejunum and ileum
mainly responsible for absorption of nutrients into the bloodstream. Once the nutrients have been
absorbed and the leftover-food residue liquid has passed through the small intestine, it then
moves on to the large intestine, or colon. The small intestine has a folded lining to absorb
nutrients; the lining of the large intestine is flatter
V.Large intestine -.

Human have a special digestive system than the other animals. We have to know how our body digest our food after having a meal. So, let's check it out.
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. -wikipedia

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

1. The Digestive system The Digestive system By: Malerie Vega Medical terminology BIO 120 Presentation 8
2. The Colon The Anal Sphincter is the ring of muscle that controls the anal opening. This opening is the anus. The ascending colon is the section following domen The cecum is the first portion of the colon. It is a blind pouch off the beginning of the large intestine. The appendix grows out of the end of the cecum Defecation is the evacuation of feces which is food that can not be digested so it is evacuated from the rectum The descending colon is the section of the colon that descends the left side of the abdomen
3. The Colon The rectum is at the end of the digestive tube that holds feces. Sigmond colon is the final section of the colon The transverse colon is the section that crosses the upper abdomen from right to left. Vermiform appendix is a small out growth out of the cecum the purpose or the function is unknown
4. Parts of the Colon The ascending colon travels up the right side of the abdomen. The transverse colon runs across the abdomen. The descending colon travels down the left abdomen. The sigmond colon is a short curving of the colon, just before the rectum.
5.
6. Function of the Colon The colon removes water, salt, and some nutrients forming stool. Muscles line the colon’s walls, squeezing its contents along. Billions of bacteria coat the colon and its contents, living in a healthy balance with the body.
7. Specifications of the Colon The colon absorbs water from the sludge while transporting it toward the rectum. In the process, the colon may also absorb harmful materials. The longer it takes for waste to pass through the colon, the greater the chance of absorbing such materials. You can tell how long waste sits in your colon by how often you poop so, the more you poop, and the faster your colon is processing material. The small intestine sucks the nutrients out of what you eat and then pours the leftover sludge into the cecum. This sludgy waste then moves from the cecum to the colon for further processing. The large intestine connects with the small intestine to the north and freedom (open air) to the south. It begins with the cecum and ends with the anus.
8. Specifications of the Colon continued The large intestine is the same thing as the large bowel. The main components of the large intestine include the cecum, appendix, colon, rectum, anal canal, and anus. The cecum is about six centimeters (cm) long and 7.5 cm wide. The ileum (of the small intestine) dumps waste material into the cecum and the cecum passes it on to the colon, specifically the ascending colon. It doesn't do so through a little tube; the cecum is continuous with the colon. The appendix helps support the immune system in two ways. It helps tell lymphocytes where they need to go to fight an infection and it boosts the large intestine's immunity to a variety of foods and drugs. The rectum is about eight inches long and serves, basically, as a warehouse for poop.
9. Description of the Colon The rectum has little shelves in it called transverse folds. These folds help keep stool in place until you're ready to go to the bathroom. When you're ready, stool enters the lower rectum, moves into the anal canal, and then passes through the anus on its way out. The anal canal is the last stop for poop and then when someone decides it's time (or the body decides for them), poop leaves the rectum, passes through the anal canal, and exits the body through the anus. The anal canal is 2.5 - 4 centimeters long, depending on the person. Its upper half is comprised of anal columns, vertical folds of tissue. Its lower half is comprised of anal valves, folds of tissue that connect the bottoms of the anal columns together. The pectinate line runs underneath the anal valves. The anus is the end of the line at this part the feces is then pushed out of the anus
10. Some Colon Conditions Hemorrhoids: These are probably the most common cause of visible blood in the lower digestive tract, especially blood that appears bright red. Hemorrhoids are enlarged veins in the anal area that can rupture and produce bright red blood, which can show up in the toilet or on toilet paper. Colon Bleeding: (Hemorrhage) Multiple potential colon problems can cause bleeding. Rapid bleeding is visible in the stool, but very slow bleeding might not be.
11. The Esophagus The peristalsis is the wave like muscular movement in the wal of the digestive system tube Anatomically and functionally, the esophagus is the least complex section of the digestive tube. The esophagus begins as an extension of the pharynx in the back of the oral cavity. It then courses down the neck next to the trachea, through the thoracic cavity, and penetrates the diaphragm to connect with the stomach in the abdominal cavity.
12. The Esophagus . First, instead of the muscular tunic being entirely smooth muscle, as it is in the stomach and intestines, the wall of the esophagus contains a variable amount of striated muscle. The esophagus is routinely exposed to rough and abrasive foodstuffs, like fragments of bone, fibrous plant leaves and Doritos.
13.
14. The EsophagusContinued When relaxed, as it is during swallowing, this muscle pulls the larynx forward and aids in routing food into the esophagus instead of the larynx. The lower esophageal sphincter is the muscle that surrounds the esophagus just as it enters the stomach. Normally, the upper and lower sphincters are closed except during swallowing, which prevents constant entry of air from the oral cavity or reflux of stomach contents.
15. Dissorders of the Esophagus heartburn and gastro esophageal reflux disease (GERD). In both cases, the lower sphincter does not close properly, allowing acid from the stomachto reflux back into the esophagus, causes a burning sensation in the chest or throat (heartburn) or additional signs such as coughing, coughing or a sensation of choking.
16.
17. Oral cavity The oral cavity consist of many smaller parts like the cheeks or gingiva which are the gums. The opening is formed by the lips food is broken down by using the teeth and a little help from saliva. the tongue is the muscle that contain the taste buds that let you taste anything that enters the oral cavity The palate is the roof of your mouth were the uvula the soft pendulum like object in the back of the mouth this is used for speech and is the location of the gag reflex
18. The Stomach The Antrum is the tapered distal end of the stomach. The cyme is the semi soft liqued that is a mixture of food and digestive fluid that passes from the stomach into the small intestine The fundus is the domed upper part of the organs such as the stomach or uterus. Hydrochloric acid secrets from the stomach to help with digestion.
