Study Notes
Cardiovascular System
- The heart is divided into 4 chambers.
- The right ventricle pumps blood into the pulmonary artery, transporting oxygen-poor blood to the lungs.
- The left ventricle pumps oxygen-rich blood to the body.
- The septum is the muscular wall that separates the left and right sides of the heart.
Heart Valves
- The tricuspid valve is a flap that lies between the right atrium and the right ventricle, preventing back-flow of blood.
- The mitral valve is located between the left atrium and the left ventricle, preventing back-flow of blood.
Blood Vessels
- Arteries carry blood away from the heart throughout the body.
- Veins carry blood towards the heart.
- Capillaries are responsible for the exchange of materials such as gases, nutrients, etc. between the blood and body.
Respiratory System
- Alveoli are tiny sacks in the lungs surrounded by capillaries where oxygen enters the bloodstream, and carbon dioxide exits.
- The trachea (windpipe) is kept open by rings of cartilage.
- The diaphragm is a sheet of muscle under the lungs that regulates the pressure inside the chest.
- The bronchial tubes split off from the trachea.
- The pharynx connects the nasal cavity and the oral cavity.
Respiration
- Respiration occurs in all cells.
- The respiratory system is responsible for moving oxygen throughout the body.
Joints and Ligaments
- Joints are places where two bones come close together and are connected by ligaments.
- Ligaments connect bone to bone.
