Biology Important Diagrams Diagram Functions Waxy Cutile: Prevents water loss Air Spaces: Allows Diffusion of gases Guard Cells: Regulate opening and closing of stomata Stomatal Pore: Control Gas exchange Chloroplast: Convert light energy into usable energy Pseudopodia: Engulfs food particles Food Vacuole: Helps in digesting the indigested food Diagram Explanation Breakdown of glucose by various pathways Mouth: Salivary glands release saliva which converts starch into maltose Stomach: Secrete HCL and convert pepsinogen to pepsin Small Intestine: Digestion completes here (Protein breakdown into ammino acids, carbs into glucose & fats into fatty acid and glycerol) Large Intestine: Absorb salt and water Liver: Secret Bile (Emulsify fat globules) Pancreas: Secret Trypsin and lipase Diagram Explanation Aorta: Carry oxygenated blood from heart to body Pulmonary Arteries: Carry de-oxygenated blood from body to lungs Pulmonary Veins: Carry oxygenated blood from lungs to heart Left atrium & ventricle: Receives oxygenated blood from lungs & Sends oxygenated blood to Aorta Right atrium & ventricle: Receives de- oxygenated blood from body & Receives de- oxygenated blood from atrium Septum: Seperates oxygenated and de- oxygenated blood Vena Cava: Carry de- oxygenated blood from body to heart Diagram Explanation Trachea: Produce mucus(also known as wind pipe) Rings of Cartilage: Prevents the wall of trachea from collapsing Diaphragm: Changes it’s shape to help thoracic cavity to expand (inhale) and contract (exhale) Alveoli: Exhange Oxygen and Carbon di-oxide in blood stream Larynx: Voice box Pharynx: Junction of food and wind pipe Pulmonary Vein: Receives oxygenated blood Pulmonary artery: Sends de-oxegenated blood Artery: Carry oxygenated blood Vein: Carry de- oxygenated blood Diagram Explanation Glomerulus: Filter the blood Tubular Part: Reabsorption of nutrients from filtrate Collecting Duct: Collects final urine and pass it to ureter Capillaries: Re- absorption of vital nutrients Bowman’s Capsule: Collects blood to filter Left Kidney: Remove waste and extra fluid Left Ureter: Urine passes through towards bladder Urinary bladder: Store Urine and empty under neuromuscular Control Urethra: Allows urine to pass outside the body Diagram Explanation Forebrain: Controls the reproductive functions, body temperature, emotions, hunger and sleep. Hindbrain functions: The three regions of the hindbrain coordinates all processes necessary for survival. These induce breathing, heartbeat, sleep, wakefulness and motor learning. Pituitary Gland: monitors and regulates many bodily functions through the hormones that it produces, including: Growth and sexual/reproductive development and function. Cerebrum: responsible for thinking, intelligence, consciousness and memory.
