Blood is involved to this network of vessel. Close Type Suited for organisms with fast metabolism; blood is circulated at a higher pressure.  Parts of the 0 Circulatory 2 System Parts of the Circulatory System 0 Heart – Chambers 1 and valves 0 Blood Vessels – 2 Arteries, Veins, 0 Capillaries Blood – RBC, 3 WBC, Platelets, Plasma Structur e of the Heart Heart Is a double pump in one organ  Heart Right side: pumps oxygen poor blood to the lungs through Pulmonary circuit. Heart Left Side: Receives oxygen-rich blood from the lungs. Then circulated to the rest of the body through systematic circuit.  Heart The right and left side if the heart is separated by a thick wall of muscle called septum. Heart Chambers; upper chambers are called atria(singular atrium) Heart Two Chambers; upper chambers are called atria(singular atrium);lower chambers are called ventricles. Heart Upper chambers receives the blood coming into the heart; Lower chambers receives the blood coming from the upper chambers. Then pumps out the blood into the other parts of the body.  Heart The heart valves are flaps of tissue that prevent blood from flowing backwards. They open when the atria or ventricles contract, and shut when it relaxes. Heart Entrance valves are called atrioventricular valves. Also known as tricuspid valve. Located between the right atrium and the right ventricle. Heart Bicuspid or mitral valve is found between the left atrium and the left ventricle. Heart Exit valves are called semilunar valves.  Blood Is Vessel a closed system through which blood is being transported to and from the body; Tubular structure. Blood Vessel 0 Arteries 1 0 Veins 2 0 Capillaries 3 2 types of blood a.

Deoxygenated blood 2 types of blood b. Deoxygenated blood Contains Carbon Dioxide & waste; Dark Red; Found in Veins; Body to H/L Arteries Carry blood away from the heart into the capillaries that connect to the tissues. Arteries Thick and Elastic walls which are strong enough to receive high-pressure blood pumped from the ventricles of the heart.  Arteries Aorta – Largest artery; thickest wall Arterioles – Smallest subdivisions of the arteries; thinner walls and less elastic connective tissues Veins Return the blood to the heart and drain the capillaries in the tissues. Veins Walls are thinner but wider than the arteries; equipped with one way valves. Veins Venules – smallest veins Capilla ries Finest and smallest of the three types of blood vessels. THANK YOU! Choose the best answer.

Varies with the size of a person. Blood An average male adult weighing 70 kilograms or 154 pounds has about 5 liters of blood. Function s of blood Transport gases, wastes, nutrients, hormones Prevents blood loss during injury Function s of blood Defense against pathogens and toxins Regulating body temperature Components of Blood  Blood Plasma 55% of blood volume; liquid part of the blood. Plasma is about 90% water. The remaining 10% are different substances. Plasma Proteins 2nd largest percentage. Plasma Proteins Albumin – most abundant plasma protein in the blood; manufactured by the liver Plasma Proteins Clotting factors - proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury. Plasma Proteins Clotting cascade Plasma Proteins Antibodies - are proteins that protect you when an unwanted substance enters your body. Plasma Proteins Antibodies - Produced by your immune system, antibodies bind to these unwanted substances in order to eliminate them from your system. Formed Element s Makes up about 45% of the blood volume. Consists of RED BLOOD CELLS, WHITE BLOOD CELLS, PLATELETS Formed Element s Makes up about 45% of the blood volume. Consists of RED BLOOD CELLS, WHITE BLOOD CELLS, PLATELETS  RED BLOOD CELLS Also known as erythrocytes Tiny concave disk- shaped cells  RED BLOOD CELLS Hemoglobin – an iron containing protein which gives the ability to carry oxygen  RED BLOOD CELLS Hemoglobin – gives the blood its characteristic red color.  WHITE BLOOD CELLS Also called Leukocytes; colorless; responsible primarily for defending the body against infections.  WHITE BLOOD CELLS Also called Leukocytes; colorless; responsible primarily for defending the body against infections. Platelets Small colorless disk- shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting. Platelets Also called thrombocytes Platelets Thrombocytopenia – number of platelets is too low; bruising and abnormal bleeding can occur. Platelets Thrombocythemia – number of platelets is too high; blood may clot excessively, causing a stroke or heart attack. Lifespan of Blood cells Red blood cells – 20 to 120 days circulating in the  Lifespan of Blood cells White blood cells – 6 to 8 hours circulating in the blood stream  Lifespan of Blood cells Platelets – survive for about 10 days They need to be replaced Constantly  Most blood components are produced in the bone marrow. THANKS!
