What else can I help you with?
How are Heart Attack and Stroke similar?
They are both blockages in the arteries that supply oxygen and nutrients to the tissues, that ultimately cause irreversible damage to either the heart or brain.
What organ system brings the blood to the body?
The cardiovascular system brings blood to the body. You have more than 50,000 miles of blood vessels in your body.
Why do most tissues have a greater supply of capillaries than veins and arteries?
Capillaries service cells, arteries and veins transport blood to and from capillaries, respectively.
One of the major characteristics of arteries supplying peripheral tissues is that they are?
elastic muscular rigid
Does blood flow more rapidly in the capillaries or in arteries?
Remember arteries come from the heart, and veins go from the organs back to the heart. Therefore, as the heart is the main pump, the arteries have the greatest pressure, so "the blood flow is more rapid in arteries."
What carries blood and nutrients to the heart?
The coronary arteries carry blood and nutrients to the tissues of the heart. They are part of the systemic circulation.
Vessels that connect arteries to veins and where the tissues exchange gases and nutrients with the blood are called?
Capillaries
What does hemoglobin bind oxygen with when it reaches the arteries?
Oxygen is bound to the haemoglobin in the blood in the lung tissues, then this oxygenated blood is returned to the heart for distribution via the arteries.
What effects are seen on the circulatory system?
When the heart stops beating the supply of blood containing nutrients and oxygen stops reaching the tissues of the body, as there is nothing to push it around the arteries. This then leads to lack of nutrients for the cells in the tissues thus the tissues start to die.
Oxygenated blood is usually carried in?
Oxygenated blood is carried in arteries, which transport blood away from the heart to various parts of the body, delivering oxygen and nutrients to tissues.
What delivers blood to your body tissues?
Blood vessels, including arteries, arterioles, and capillaries, deliver blood to your body tissues. These vessels carry oxygen and nutrients to cells throughout the body, allowing for essential functions and processes to occur.
Is blood in arteries always oxygen rich?
Yes, blood in arteries is typically oxygen-rich because the arteries carry blood away from the heart to deliver oxygen to the body's tissues. Oxygenated blood is pumped from the heart through the arteries to provide nutrients and oxygen to cells.
Why do arteries have thick walls?
Arteries have thick walls to withstand the high pressure of blood flow from the heart to the rest of the body. The thick walls help maintain the shape and structure of the arteries, allowing them to efficiently transport oxygen and nutrients to tissues and organs.
What type of blood is usually transported in arteries?
Oxygenated blood with a high concentration of oxygen is usually transported in arteries. This blood is pumped by the heart to various parts of the body for distribution to tissues and organs.
Do the arteries carry blood rich in food and oxygen?
Yes. Oxygen directly, the veins get the food first but it must pass through the lungs and the heart to get to the arteries (and thence to the cells).
How are Heart Attack and Stroke similar?
They are both blockages in the arteries that supply oxygen and nutrients to the tissues, that ultimately cause irreversible damage to either the heart or brain.
What is the role of the capillaries?
Capillaries are very small blood vessels found within the tissues of the body. Its primary role is to transport blood from arteries to the veins.
