Help ASAP please! 1. Define ARTERIES
2. Define Veins
3. Define Capillaries
4. What two parts is blood separated into?
5. How much blood is in the human body?

The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium

Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Arteries and veins are two of the body's main type of blood vessels. These vessels are channels that distribute blood to the body.

n humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets.

Scientists estimate the volume of blood in a human to be approximately 7 percent of body weight. An average adult with a weight of 150 to 180 pounds will contain approximately 1.2 to 1.5 gallons (4.7 to 5.5 liters) of blood

Explanation:

ur welcome.

1. The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium.

2. 1 : blood vessel especially : any of the tubular branching vessels that carry blood from the capillaries toward the heart. 2a : any of the vascular bundles forming the framework of a leaf.

3. Capillaries are tiny blood vessels connecting arteries to veins. These blood vessels carry oxygen and nutrients to individual cells throughout the body.

4. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets.

5. The average adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood circulating inside their body, said Dr. Daniel Landau, a hematologist and oncologist at the University of Florida Cancer Center – Orlando Health. If you had no blood, you'd weigh 8 to 10% less.
