What is the anatomy and physiology of the circulatory system?

What is the anatomy and physiology of the circulatory system?

The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.

What is anatomy and physiology of heart?

The heart has a middle muscular layer, the myocardium, made up of cardiac muscle cells, and an inner lining called the endocardium. The inside of the heart (heart cavity) is divided into four chambers – two atria and two ventricles – separated by cardiac valves that regulate the passage of blood.

What is the function of heart PDF?

The heart is a muscular organ that acts like a pump to continuously send blood throughout your body. The heart is at the centre of the circulatory system. This system consists of a network of blood vessels, such as arteries, veins, and capillaries. These blood vessels carry blood to and from all areas of the body.

What is the basic physiology of the heart?

The heart itself is made up of 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed.

What is the anatomy of heart?

The heart is made up of four chambers: two upper chambers known as the left atrium and right atrium and two lower chambers called the left and right ventricles.

What is anatomy of the heart?

Your heart is divided into four chambers. You have two chambers on the top (atrium, plural atria) and two on the bottom (ventricles), one on each side of the heart. Right atrium: Two large veins deliver oxygen-poor blood to your right atrium. The superior vena cava carries blood from your upper body.

What is the anatomy of the heart?

What is anatomy and physiology examples?

For example, an anatomist may study the types of tissues found in different parts of the heart, while a physiologist may study how the heart regulates blood flow to supply oxygen to other organs in the body.

What are the 4 parts of the heart?

The heart has four chambers: two atria and two ventricles.

• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
• The right ventricle pumps the oxygen-poor blood to the lungs.
• The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

What is cardiac anatomy & physiology?

Cardiac Anatomy & Physiology Circulatory System Cardiovascularand lymphatic systems make up the circulatory system a vast network of organs and vessels responsible for the flow of: The Cardiovascular system • Blood • Blood vessels • Heart The Lymphatic system

What is the structure of the human circulatory system?

Structure of the human circulatory system The human circulatory system consists of: Blood vessels, Heart, Blood Blood vessels: Arteries: blood vessels that carry blood away from the heart in pulses. It has a thick wall and small lumen.

How does the circulatory system work?

The heart is at the centre of the circulatory system. This system consists of a network of blood vessels, such as arteries, veins, and capillaries. These blood vessels carry blood to and from all areas of the body. An electrical system regulates the heart and uses electrical signals to contract the heart’s walls.

What is the systemic circuit of the heart?

The systemic circuit consists of vessels that lead from the left ventricle to the body cells and back to the heart, 48 CHAPTER 5 Anatomy and Physiology of the Cardiovascular System
