This network supplies tissues in the body with oxygen and other nutrients, transports hormones, and removes unnecessary waste products. ]]> 2018-12-09 05:09:15 UTC https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312586219 THE HEART honeytaoc https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312586418 The heart is made of specialized cardiac muscle tissue that allows it to act as a pump within the circulatory system.
The human heart is divided into four chambers. There are one atrium and one ventricle on each side of the heart. The atria receive blood and the ventricles pump blood.

Arteries carry blood away from the heart and into capillaries, providing oxygen (and other nutrients) to tissue and cells. Once oxygen is removed, the blood travels back to the lungs, where it is reoxygenated and returned by veins to the heart. ]]> 2018-12-09 05:19:32 UTC https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312586794 BLOOD honeytaoc https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587025  Blood is composed of a straw-coloured fluid, plasma, and huge numbers of blood cells that float in the plasma. Of the two main types of blood cell, red blood cells carry oxygen to the body’s tissues, and white blood cells help defend the body against infection. Blood also transports nutrients, proteins needed for blood clotting, and waste products. ]]> 2018-12-09 05:23:20 UTC https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587025 BLOOD CLOTTING honeytaoc https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587077  If a blood vessel is damaged, a clot forms to stop blood leaking. First, platelets stick together to form a plug that stops the leak. At the same time, a complex sequence of chemical events in the blood leads to the production of long strands of a protein called fibrin. These bind the blood cells and debris together to form a gel-like clot that gradually solidifies. The solid clot remains until the blood vessel has been repaired. ]]> 2018-12-09 05:24:10 UTC https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587077 honeytaoc https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587192  A drop of blood contains millions of red cells, and each cell contains 250 million molecules of a substance called haemoglobin. In the lungs, oxygen binds to haemoglobin, but in the tissues the oxygen is released again. Several types of white blood cell exist, and all are important to the body’s immune system. Platelets are tiny cells that are needed for blood clotting. ]]> 2018-12-09 05:25:44 UTC https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587192 BLOOD CELLS honeytaoc https://padlet.com/honeytaoc/4bdps5r1ytxl/wish/312587218  A drop of blood contains millions of red cells, and each cell contains 250 million molecules of a substance called haemoglobin.
