(1ai)
Health according to the World Health Organization (WHO is defined as a state of complete physical mental and social well-being and not merely the absence of disease or infirmity.

(1aii)
(i) Personal lifestyle choices such as diet physical activity tobacco and alcohol use and sexual practices can significantly impact health.
(ii) Factors like socioeconomic status education employment and social support systems play a vital role in health outcomes.
(iii) Physical Environment: The quality of air water and sanitation as well as the availability of healthcare facilities can influence the overall health of individuals.
(iv) Genetics and Biology: Genetic factors inherited traits and biological characteristics can have an impact on an individual’s susceptibility to certain diseases or conditions.

(1bi)
(i) Digestion: The small intestine receives partially digested food from the stomach and continues the process of breaking down complex food particles into smaller molecules. It utilizes enzymes produced by the pancreas and the small intestine itself to aid in the breakdown of proteins carbohydrates and fats.
(ii) Absorption: The inner lining of the small intestine contains numerous tiny finger-like projections called villi. These villi increase the surface area available for absorption. The small intestine absorbs most of the digested nutrients including glucose amino acids and fatty acids into the bloodstream.
(iii) Secretion: The small intestine secretes various enzymes mucus and hormones necessary for digestion and absorption. It releases digestive enzymes and bile into the small intestine to facilitate the breakdown of nutrients.

-Chemical Digestion-
(PICK ANY TWO)
(i) Involves the breakdown of complex food molecules into simpler forms through chemical reactions facilitated by enzymes.
(ii) Occurs primarily in the mouth (with saliva stomach and small intestine.
(iii) Examples of chemical digestion include the breakdown of proteins into amino acids carbohydrates into sugars and fats into fatty acids and glycerol.
(iv) Requires the presence of specific enzymes for the breakdown of different types of nutrients.

-Mechanical Digestion-
(PICK ANY TWO)
(i) Involves the physical breakdown of food into smaller particles through chewing churning and mixing actions.
(ii) Occurs primarily in the mouth (with teeth stomach and small intestine.
(iii) Examples of mechanical digestion include chewing stomach contractions and the segmentation movement of the small intestine.
(iv) Relies on physical force such as teeth grinding stomach contractions and peristalsis to break down and mix the food.

(1c)
(i) Ultrafiltration: Ultrafiltration is a vital process that occurs in the kidneys. It is the first step in urine formation and involves the filtration of blood through specialized filters known as glomeruli. The pressure of blood forces small molecules like water glucose amino acids salts and waste products to pass through the glomerular capillaries and enter the renal tubules. Larger molecules such as blood cells and proteins are retained in the bloodstream. This process ensures that only small molecules are filtered into the urine while important substances are reabsorbed later in the tubules.

(ii) Selective Reabsorption: Selective reabsorption occurs in the renal tubules of the kidneys. After the initial filtration process essential substances such as glucose amino acids water and salts are selectively reabsorbed into the bloodstream. This process helps maintain the body’s homeostasis by conserving valuable substances that the body needs rather than excreting them in the urine. The selective reabsorption process is regulated by specific transporters and hormones to ensure an appropriate balance of substances in the body.

(iii) Vasoconstriction: Vasoconstriction is the narrowing or constriction of blood vessels. It occurs when the smooth muscles around the blood vessels contract causing a decrease in their diameter. This constriction reduces blood flow and can be useful in certain situations such as during bleeding or when redirecting blood to specific areas of the body. Vasoconstriction is regulated by the nervous system and various hormones and plays a crucial role in regulating blood pressure blood flow distribution and body temperature.
