Blood
State the name of the fluid connective tissue consisting of blood cells, dissolved nutrients, and ions suspended in watery liquid
What is Blood?
State the four chambers of the heart
what are The right atrium, right ventricle, left atrium, and left ventricle?
Blood Vessels with just one cell thick walls
What is Capillaries?
The pathway that blood takes to and from the lungs, where it picks up oxygen and releases carbon dioxide.
What is pulmonary circulation?
Power house of the cell
what is Mitochondria?
Blood consists of plasma (the liquid component) and formed elements, including red blood cells, white blood cells, and platelets.
What are the main components of blood?
What is the function of arteries?
Arteries carry oxygenated blood away from the heart to the body's tissues.
An artery that brings deoxygenated blood to the lungs.
What is a Pulmonary Artery?
The circulation of blood from the left side of the heart to the body and back to the right side of the heart.
What is systemic circulation?
A molecule that makes up the building blocks of DNA and RNA, composed of a 5-carbon sugar, a phosphate group, and a nitrogenous base.
What is a nucleotide?
contains hemoglobin, which carries oxygen from the lungs to the rest of the body and transports carbon dioxide back to the lungs.
What is the function of red blood cells
Describe the function of veins
Why do Veins return deoxygenated (oxygen-depleted) blood from the body's tissues back to the heart?
Veins that brings blood from the top 1/3 of the body to the heart.
What is Superior Vena Cava
What is circulatory system?
The circulatory system is a system that transports blood, oxygen, carbon dioxide, nutrients, hormones, and waste products to and from the cells of the body.
State the cell theory.
All living organisms are made of cells; cells are the basic unit of life; and cells arise from pre-existing cells.
white blood cells, lymphocytes, cells that eliminate pathogens and foreign materials from body
What are leukocytes?
Describe the function of capillaries
Why do Capillaries are tiny blood vessels where oxygen and nutrients are delivered to cells, and waste products like carbon dioxide are picked up?
The largest Artery of our body
What is Aorta?
What are the main parts of the circulatory system?
The main parts of the circulatory system are heart, blood vessels, and blood.
Describe the primary difference between plant and animal cells
Why do plant cells have a cell wall, chloroplasts, and a large central vacuole, which animal cells lack?
This iron-containing protein in red blood cells binds to oxygen, giving blood its red color, and can carry up to four oxygen molecules at once
What is hemoglobin?
Describe the function of the valves in the heart
why do Heart valves ensure that blood flows in one direction, preventing it from flowing backward between the chambers?
Brings oxygen-rich blood to the pericardium
What is coronary circulation ?
Coronary circulation is the flow of blood to the heart muscle with oxygen and nutrients. It uses coronary arteries to bring oxygenated blood and coronary veins to carry away wastes.
the "universal solvent" in biological systems
What is water? (Water is considered the universal solvent because its polarity and ability to form hydrogen bonds allow it to dissolve a wide range of substances, making it vital for biochemical reactions.)
