2025/2026 Exam Questions and Correct
Answers | New Update
Biological Hierarchy - 🧠 ANSWER ✔✔Organisms are living things
consisting of one cell.
Cell is the smallest unit of life that can reproduce on its own.
Unicellular organism such as amoeba, are made up of one cell.
Multi-cellular organism,the cells are grouped together into Tissues.
,Tissues forms Organs( such as the Heart)
Organs are grouped into Organ System (such as the Digestive or
Respiratory Systems).
Organ systems are open and will have a number of inputs and outputs.
Anatomical Terminology - 🧠 ANSWER ✔✔Used to describe the location
and Morphology of a particular structure.
Used common terms to describe spatial relationships, often in opposite
pairs.
Refers to position of a structure in an organism that is upright with respect
to its environment.
Anatomical Terminology 2 - 🧠 ANSWER ✔✔SUPERIOR, above e.g. the
eyes are superior to the nose.
,INFERIOR below
ANTERIOR front e.g. In humans the eyes are anterior with respect to the
ears, conversely the ear is posterior to the eyes.
POSTERIOR back
DORSAL closer to the back of an object. e.g. the spine is dorsal to the
stomach, while the stomach is more ventral..
VENTRAL closer to the front of an object.
MEDIAL refers to the middle of a structure.
LATERAL refers to further from the center or closer to the outer
boundaries.

, PROXIMAL is close
DISTAL is further away e.g. the index finger is more proximal to the hand
than the elbow, which is more distal to the hand.
Respiratory System - 🧠 ANSWER ✔✔powerful muscles force oxygen-rich
air into the lungs and carbon dioxide-rich air out if the body.
Mammalian cells require oxygen for glucose metabolism and release
carbon dioxide(CO 2) as a by product.
LUNGS where gas exchange takes place, humans have 2 lungs a right and
a left, with the right lung slightly larger due to the heart's placement in the
chest cavity.
RIGHT LUNG has three lobes and the LEFT has two.
