Answer:
a) Heart
b)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.
c)Saliva is produced in and secreted from salivary glands. The basic secretory units of salivary glands are clusters of cells called an acini. These cells secrete a fluid that contains water, electrolytes, mucus and enzymes, all of which flow out of the acinus into collecting ducts.
d)Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
e)Carbohydrates. Carbohydrates are digested in the mouth, stomach and small intestine. Carbohydrase enzymes break down starch into sugars. The saliva in your mouth contains amylase, which is another starch digesting enzyme.
f)It's digested in your mouth, stomach, and small intestine before it's released into your bloodstream as individual amino acids. You can maximize the nutrients you get from protein sources by eating complete proteins and adopting certain habits, such as chewing thoroughly before swallowing
g)Blood enters the kidneys through renal arteries. These arteries branch into tiny capillaries that interact with urinary structures inside the kidneys (namely the nephrons). Here the blood is filtered. Waste is removed and vital substances are reabsorbed back into the bloodstream.
h) I am having doubt in this. But I think it should be kidney
