The circulatory system transports nutrients, gases, hormones, blood cells, and waste throughout the body. The three main circulating fluids are blood, tissue fluid, and lymph. Blood is transported in arteries and veins, and contains plasma and cellular components like red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide via hemoglobin. White blood cells help fight infection through processes like phagocytosis. Platelets help the blood clot to prevent blood loss after an injury. Together, these components and the circulatory system enable essential functions and homeostasis in the human body.
CLIL: Biology; blood cells.
Red blood cells carry oxygen throughout the body and live for about 120 days. White blood cells help fight infection as part of the immune system. Platelets help the blood clot. Blood is made up of plasma, which allows cells to move, and four main cell types - red blood cells, white blood cells, platelets, and plasma. Arteries carry oxygenated blood away from the heart while veins carry deoxygenated blood back to the heart. Capillaries are where gas exchange occurs between blood and tissues. The immune system responds to infections through a coordinated response between white blood cells and antibodies.
Cardiovascular system
The cardiovascular system includes the heart and blood vessels that circulate blood throughout the body. The heart is a muscular pump about the size of a fist that beats over 100,000 times per day to pump blood. Blood carries oxygen, nutrients, hormones and waste products and helps regulate temperature, pH, and defend against toxins. The major components of blood are plasma, red blood cells, white blood cells, and platelets. Heart disease is the leading cause of death and includes conditions like atherosclerosis, heart attacks, heart failure, and stroke. Risk factors for cardiovascular disease include tobacco use, diet, exercise, diabetes, and heredity.

Platelets assist in clotting blood when injuries occur. Together these components maintain homeostasis, transport nutrients and waste, and protect the body from pathogens.
Haemopoiesis
Hematopoiesis is the process where blood cells are produced in the bone marrow from hematopoietic stem cells. In adults, red blood cells, white blood cells, and platelets are produced in the bone marrow from pluripotent stem cells. The stem cells differentiate into the various cell lineages through the effects of growth factors and cytokines. Erythropoietin regulates red blood cell production in response to tissue oxygen levels while granulocyte macrophage colony-stimulating factor regulates white blood cell production. T and B lymphocytes mature in different areas with T cells maturing in the thymus and B cells maturing in the bone marrow and spleen.

The heart has four chambers and uses valves to pump oxygenated blood from the lungs and deoxygenated blood to the lungs. Blood flows through arteries, capillaries, and veins. The respiratory system exchanges gases through the nose, pharynx, trachea, bronchi, and alveoli in the lungs. Breathing is controlled by the medulla oblongata and diaphragm. Smoking damages lungs and increases risk of diseases like cancer, emphysema, and bronchitis.

Cardiovascular system presentation.bert
The cardiovascular system consists of the heart, blood, and blood vessels. The document provides details on their structure and function. It describes the components of blood including red blood cells, white blood cells, platelets, and plasma. It discusses the formation of blood cells and hemoglobin's role in oxygen transport. It also outlines the anatomy of the heart including chambers, valves, conduction system, and cardiac cycle. Blood pressure regulation and blood flow through arteries, arterioles, and capillaries are also summarized.
Chapter 37 lecture- Circulatory & respiratory
The circulatory system transports blood throughout the body using the heart and blood vessels. The heart has four chambers and pumps deoxygenated blood to the lungs and oxygenated blood to the body. Blood consists of plasma, red blood cells, white blood cells, and platelets. Red blood cells carry oxygen, white blood cells fight infection, and platelets help with clotting. The lymphatic system drains fluid from tissues and returns it to the blood.
OLLI Circulatory_System.pdf
The circulatory system transports oxygen, nutrients, hormones, and removes waste through two circuits - the pulmonary and systemic circuits. The pulmonary circuit transports deoxygenated blood to the lungs and the systemic circuit transports oxygenated blood to the rest of the body. The heart pumps blood through arteries, veins, and capillaries which allow for gas and nutrient exchange. Blood consists of plasma, red blood cells, white blood cells, and platelets.

Blood is the liquid that circulates through the body, carrying oxygen and nutrients to cells and waste products away. It flows through two circulation loops - pulmonary circulation carries blood to the lungs to receive oxygen, then systemic circulation distributes oxygenated blood to the entire body. Blood is produced in the bone marrow from stem cells and has several components - red blood cells carry oxygen, platelets help clotting, plasma is fluid that carries cells and proteins, and white blood cells defend against infection. Blood must be compatible between donor and recipient for safe transfusion to treat conditions like anemia or injury-related blood loss.
The circulatory system 2018
The circulatory system transports blood throughout the body using blood vessels. Blood carries oxygen, nutrients, hormones and waste products as it circulates from the heart through arteries and veins, with an exchange of substances occurring between blood and body cells in capillaries. Some organisms have a single circulation where blood passes through the heart once, while mammals like humans have a double circulation with blood passing through the heart twice per circuit. Heart disease can be caused by factors like lack of exercise, poor diet, smoking and genetics, and treated through lifestyle changes, medication, procedures like angioplasty, or surgery. The lymphatic system works with the circulatory system to transport lymph and help fight infection.
Basic blood
Hematology is the study and treatment of blood. The main components of blood are plasma, red blood cells, white blood cells, and platelets. Red blood cells contain hemoglobin and carry oxygen, while white blood cells help fight infection. Platelets assist in clotting. A complete blood count test analyzes levels of blood components. Blood disorders include anemia, blood clots, and cancers that affect blood cells. Blood functions include transporting oxygen, nutrients, hormones, waste removal, temperature regulation, clotting, and immune defense.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Histololgy of Female Reproductive System.pptx

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
