The document summarizes investigations of the circulatory system. It describes the major components of the circulatory system and how blood is transported throughout the body. It also compares circulatory systems across different animal phyla, including how the human circulatory system has evolved to develop separate oxygenated and deoxygenated blood flows through four chambered hearts.
This presentation is a combination of different slides which I re-purposed. I included a reference of all the slides I used at the end of my presentation.
A powerpoint designed for the South African Life Sciences syllabus for grade 11. Includes information about blood and it's transportation, the human heart, the lymph system etc. Hope it helps :)

A transport system is a means by which materials are moved ('transported') from an exchange surface or exchange surfaces to cells* located throughout the organism.
Circulation BloodVessels Heart Blood Diseases Circulatory System
2. Overview of Circulation Pulmonary circulation: blood flow between the heart and lungs Systemic circulation: blood flow from heart to rest of the body Cardiac circulation: blood flow within the heart
hey this is VEDIKA AGRAWAL
This topic is to explain you basics of cardiovascular system mainly focusing on circulatory system i.e. systemic circulation pulmonary circulation and also portal circulation of all types.
some tricks and also there to aid learning
also there is video for easy understanding

1. Investigations of the Circulatory System Presented by: Tiesha Miller and Jillian McClennen
2. What is the Circulatory System The circulatory system is the network of flexible tubes that carry blood throughout the body. The circulatory system includes the heart, lungs, arteries, arterioles (small arteries), and capillaries (very tiny blood vessels). The blood vessels carry oxygen- and nutrient-rich blood throughout the body.
3.
4. These are the blood vessels that carry oxygen- and nutrient-depleted blood back to the heart and lungs.
12. Circulatory system in 5 Representative Animals Cnideria Nematode Annelida Mollusca Chondrichthye
13.
14. Cnideria Has an open circulatory system. In this type of system, there is neither a true heart nor capillaries. Blood vessels that act as pumps to force the blood along.
15. Continuation These vessels join directly with open sinuses. "Blood," actually a combination of blood and interstitial fluid called 'hemolymph', is forced from the blood vessels into large sinuses, where it actually baths the internal organs.
16. Nematode In nematodes, there is a circulatory system but they have pseudocoel fluids that accomplish a similar circulation throughout the body.
17. Annelids have a closed circulatory system with more than one heart that pumps in large vessels that branch into smaller vessels flowing through the organs. Blood is confined to vessels and interstitial fluid do not fuse, and muscular vessels that function as hearts.
21. Osteichthyes Osteichthyes have a two chamber heart. They have one atrium & one ventricle. An atrium receives blood into the heart and drives it into a ventricle for pumping the blood away from the heart. The ventricle muscular chamber pumps blood out of the heart and into the circulatory system. The pumped blood goes to the gills of the Osteichthyes.
22.
23. The capillaries end up converging into arteries that will eventually carry out blood throughout the body and organs. Blood flows through the capillary beds and drops blood pressure. Capillary beds are extremely small blood vessel located within the tissues of the body.
24.
25.
26. A chamber of the heart contracts when an electrical impulse moves across it. These electrical gestures begin in a small parcel of highly specialized cells in the right atrium or the sinoatrial node (SA node), also called the sinus node.
27.
28.
29. They both have 2 atria & 2 ventricles. This gives them the ability to complete separation of oxygenated and deoxygenated blood. This allows an easy access of oxygen to travel through the body and cells. The right side of the heart drives pulmonary circulation while the other dives systemic circulation.
