Cardiovascular System[edit]
The cardiovascular system, also known as the circulatory system, is an organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
Components[edit]
The cardiovascular system consists of the following major components:
Heart[edit]
The heart is a muscular organ that pumps blood through the blood vessels of the circulatory system. It is located in the thoracic cavity, between the lungs, and is divided into four chambers: the left and right atria and the left and right ventricles.
Blood Vessels[edit]
Blood vessels are the channels through which blood is distributed to body tissues. There are three major types of blood vessels:
- Arteries: Vessels that carry blood away from the heart.
- Veins: Vessels that carry blood towards the heart.
- Capillaries: Microscopic vessels where the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances occurs between blood and surrounding tissues.
Blood[edit]
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells and transports waste products away from those same cells. It is composed of red blood cells, white blood cells, platelets, and plasma.
Function[edit]
The primary function of the cardiovascular system is to transport nutrients, gases, and waste products around the body. It also plays a role in maintaining body temperature and pH balance, and in protecting the body from disease.
Circulation[edit]
The cardiovascular system is responsible for two types of circulation:
- Pulmonary circulation: The flow of blood from the heart to the lungs and back to the heart.
- Systemic circulation: The flow of blood from the heart to the rest of the body and back to the heart.
Disorders[edit]
Cardiovascular disease is a class of diseases that involve the heart or blood vessels. Common disorders include:
