The cup-shaped part of nephron which receives the glomerular filtrate is called Bowman’s capsule.

Several collecting ducts unite to form larger ducts that empty urine into a calyx at the tip of the renal pyramid. 

 Excess water is excreted from plants through the stomata in leaves.  Plants can get rid of excess water by transpiration and guttation.

Waste products are stored as resins in old xylem plants. Some plant wastes are very useful to human beings, e.g. rubber, latex, gum, resins and essential oils like eucalyptus or sandalwood oil. 

Tricuspid valves are present in between right atrium and right ventricle.

Deoxygenated (without oxygen) blood flows from the right atrium to the right ventricle and then, right ventricle pumps blood into the pulmonary artery. The pulmonary artery carries deoxygenated blood to the lungs, where it is supplied with fresh oxygen and carbon dioxide is removed.

The shoot tip of a plant receives water through vessels and tracheids.

A uriniferous tubule/nephron is a long tubule differentiated into four regions – Bowman’s capsule, proximal convoluted tubule, loop of Henle and distal convoluted tubule. Collecting ducts are the larger tubes, each receiving the collecting tubules of several nephrons. Collecting duct does not form a part of the uriniferous tubule.

Left ventricle is the most muscular chamber because it pumps out blood to the entire body tissues, through the aorta.

The loss of water in the form of vapours from the aerial parts of a plant is known as transpiration. It helps in (1) absorption and upward movement of water and minerals dissolved in it from roots to leaves (2) temperature regulation

Gaseous waste is eliminated from plants through stomata.

Systole is the period of contraction of the ventricles of the heart that occurs between the first and second heart sounds. Systole causes the ejection of blood from the ventricle into the aorta and the pulmonary trunk.

Ultrafiltration takes place in glomerulus.

Sieve tubes help in the bidirectional translocation of minerals. They are elongated, food-conducting cells in phloem in angiosperms.

The purpose of making urine is to filter out waste products from the blood. Nitrogenous waste such as urea or uric acid, excess water and toxic substances are removed from blood in the kidneys. CO₂ is removed from the blood in the lungs.
