CIRCULATORY SYSTEMBy: Ryan Hall & Alex Hernandez

Anatomy

The heart, blood, and blood vessels (capillaries, veins, and arteries) make up the Circulatory System

The Heart

The heart is an organ that relaxes and contracts 70 to 80 times per minute to pump blood throughout the body.

The heart takes deoxygenated blood from the veins and, using the lungs, pumps oxygenated blood through many arteries.

The Heart

The Blood

The blood travels through blood vessels. Things like nutrients, water, O2, CO2,

salts, and waste products are transported through the blood.

The blood also helps with bodily defenses.

The Blood

Blood Vessels

All arteries carry blood from the heart to all other organs.

Veins carry deoxygenated blood back to the heart.

The capillaries allow for gaseous exchange between the capillaries and tissue fluids

Blood Vessels

Medical Issues

Heart disease, aneurysms, high blood pressure, varicose veins, heart-attacks, heart burns, vascular disease, and heart bypasses are all things that can occur because of problems in the cardiovascular system.

Aneurysms

A brain aneurysm is when the artery that supplies blood to the brain has a weak wall.

If the aneurysm ruptures, it sends blood to the school and can case a stroke.

Heart Bypass

Heart Bypasses occur when coronary arteries are blocked and those are treated by finding an alternative path to the heart.

Other Medical Issues

Digestive System

The digestive system provides the heart with nutrients so the heart can keep beating.

The circulatory system takes the nutrients throughout the body through blood.

Respiratory System

This system provides all the oxygen in the blood that is then transported throughout the body by the circulatory system.

Muscular System

Cardiac muscle makes up the heart. Smooth muscle makes up blood vessels.
