Blood, heart, and the blood vessels. Blood, in itself, has four components: Red blood cells, white blood cells, platelets, and plasma. The heart has four chambers. The heart is located here, as you can see, just slightly to the left centre of the chest, approximately the size of our fists, and that's in the centre of the chest now. It has two upper chambers and two lower chambers. The upper chambers are called the atria and the lower chambers are called the ventricles. The heart also has valves. In this model here, you can see the valves. Now, we have atrial-ventricular valves that separate the atria and the ventricles, so the upper and lower chambers. We also have semilunar valves and pulmonary valves. Okay, so these are the valves just annotated here. This model represents heart circulation. The right-hand side of the blood from the upper and lower body via the veins, and that's called venous return, and this is the de-oxygenated blood, and it's returned to the lungs here via the pulmonary artery. The left-hand side, oxygen comes from the lungs via the pulmonary vein and is ejected back into the body all around the body by the aorta, it's this structure here.
Components of the Circulatory System
This guide provides an overview of the circulatory system, focusing on the composition of blood, the structure of the heart, and the role of blood vessels in circulation.
Blood Composition
Blood comprises four main components:
- Red blood cells (RBCs)
- White blood cells (WBCs)
- Platelets
- Plasma
Anatomy of the Heart
The heart, located slightly to the left center of the chest and about the size of a fist, has four chambers:
- Two upper chambers called the atria
- Two lower chambers called the ventricles
Heart Valves
The heart contains several types of valves:
- Atrial-ventricular valves between the atria and ventricles
- Semilunar valves and pulmonary valves
Heart Circulation Model
The heart circulates blood in two main pathways:
- The right side receives deoxygenated blood from the body and sends it to the lungs via the pulmonary artery.
- The left side receives oxygenated blood from the lungs via the pulmonary vein and distributes it throughout the body via the aorta.
