Rib Cage
Which blood vessel carries oxygenated blood from the placenta to the fetus?
Ductus arteriosus
Umbilical arteries
Foramen ovale
Umbilical vein
Which hormone is primarily responsible for maintaining the endometrial lining in early pregnancy?
Oestrogen
Progesterone
Prolactin
Relaxin
Where does fertilisation typically occur?
Cervix
Uterus
Fallopian Tube
Vagina
Which structure prevents the backflow of blood from the left ventricle into the left atrium?
Aortic valve
Pulmonary valve
Mitral (bicuspid) valve
Tricuspid valve
During pregnancy, plasma volume increases. This commonly leads to:
Hypertension
Physiological Anaemia
Dehydration
Decreased cardiac output
What is the primary role of the lungs during fetal circulation?
To oxygenate the fetal blood
To remove carbon dioxide from fetal blood
To provide a high-resistance pathway that diverts most blood through the ductus arteriosus
To store amniotic fluid for exchange with the placenta
Which organ is responsible for filtering and removing metabolic waste from the blood?
Liver
Kidneys
Spleen
Pancreas
Which hormone stimulates milk production?
Oxytocin
Prolactin
Oestrogen
Progesterone
The central nervous system consists of:
Brain and cranial nerves
Spinal nerves and spinal cord
Brain and spinal cord
Peripheral nerves
Which structure prevents food entering the trachea during swallowing?
Pharynx
Vocal cords
Epiglottis
Uvula
Maternal blood pressure in early pregnancy typically
Remains unchanged
Increases significantly
Falls slightly due to decreased vascular resistance
Becomes unstable
What is the primary function of red blood cells?
Fight infection
Form blood clots
Transport Oxygen
Produce antibodies
The primary function of the small intestine is:
Absorption of water
Storage of waste
Production of digestive enzymes
Absorption of nutrients
Which maternal adaptation helps protect against postpartum haemorrhage?
Reduced platelet count
Increased clotting factors
Decreased fibrinogen
Vasodilation in third trimester
Which hormone is responsible for softening ligaments and joints in pregnancy?
Oxytocin
Oestrogen
Relaxin
Prolactin
Cardiac output increases in pregnancy mainly due to:
Reduced stroke volume
Increased heart rate and plasma volume
Reduced blood volume
Decreased renal perfusion
Which gland is responsible for producing cortisol?
Thyroid gland
Pancreas
Pituitary gland
Adrenal glands
What is the main function of the lymphatic system?
Produce digestive enzymes
Oxygenate blood
Transport hormones
Drain excess fluid and support immune defence
During pregnancy, which change in the immune system helps the mother’s body accept the fetus?
The immune system becomes more inflamed
The immune system shifts toward a more anti-inflammatory response
The body increases its attack on foreign cells
The immune system becomes stronger at killing cells
Pregnant women are more prone to urinary tract infections due to:
Reduced bladder size
Ureteral dilation and urinary stasis caused by progesterone
Increased renal filtration
Higher urine pH
In pregnancy, the glomerular filtration rate (GFR):
Decreases by 50%
Remains unchanged
Increases due to higher renal blood flow
Drops only in the third trimester
Which body system is primarily responsible for regulating blood pH and carbon dioxide levels?
Digestive System
Respiratory System
Muscular System
Nervous System
What is the primary function of the endocrine system?
To support the body structure
To transmit nerve impulses
To regulate bodily functions with hormones
To transport oxygen
Which of the following best describes the role of the peripheral nervous system (PNS)?
To process and interpret information in the brain
To store memories and coordinate thinking
To carry messages between the brain/spinal cord and the rest of the body
To protect the brain with cerebrospinal fluid
