The circulatory system is composed of the heart and blood vessels , including arteries, veins, and capillaries.
What are the 10 organs of the circulatory system?
- Integumentary system. Skin of head and neck. Skin of head. Skin of nose. Skin of mouth. Skin of neck. Ear. Right ear. Left ear. ...
- Cardiovascular system. Heart. Cardiac fat. Chambers of heart. Left atrium and auricle. Left atrium. Left auricle. Right atrium and auricle. Right atrium.
What are the organs of the circulatory system and their functions?
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic) . The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
What are the 5 major parts of the circulatory system?
- Blood. Blood consists of:
- The heart. The heart pumps blood around the body. ...
- The right side of the heart. ...
- The left side of the heart. ...
- Blood vessels. ...
- Arteries. ...
- Capillaries. ...
- Veins.
What are the 3 types of circulation?
- Systemic circulation.
- Coronary circulation.
- Pulmonary circulation.
What is the circulatory system also known as?
The cardiovascular system is sometimes called the blood-vascular , or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.
What is the best definition of circulatory system?
The system that contains the heart and the blood vessels and moves blood throughout the body . This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products. The lymph system, which connects with the blood system, is often considered part of the circulatory system.
What are the steps of the circulatory system?
- The blood first enters the right atrium.
- The blood then flows through the tricuspid valve into the right ventricle.
- When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
What are 4 functions of the circulatory system?
- Circulates OXYGEN and removes Carbon Dioxide.
- Provides cells with NUTRIENTS.
- Removes the waste products of metabolism to the excretory organs for disposal.
- Protects the body against disease and infection.
- Clotting stops bleeding after injury.
What’s the main artery called?
The largest artery is the aorta , the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
Why the circulatory system is important?
Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells , and removes waste products, like carbon dioxide.
What the two major components of blood are?
- Erythrocytes, also known as red blood cells (RBCs)
- Leukocytes, also known as white blood cells (WBCs)
- Platelets.
What is the largest artery in the body?
Aorta Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
How does blood circulate in the human body?
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
What are the two types of blood circulation in human body?
1. There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation . Pulmonary circulation moves blood between the heart and the lungs.
How the circulatory system works with the digestive system?
(1) Inhales (breathes in) Oxygen – good for the body – gives it to the Circulatory System to be transported throughout the body through the blood. (1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
