Answer:
The correct option is : a. serous fluid in the pericardial cavity
Explanation:
The heart is enclosed in a sac containing the heart, known as the pericardium. The pericardium has two layers- fibrous and serous layer.
The serous layer of the pericardium produces and secretes the pericardial fluid into the pericardial cavity.
The pericardial fluid is a lubricating serous fluid present in the pericardial cavity. It reduces the friction caused between the pericardial membranes by lubricating the epicardial surface.
Low calorie food intake can lead to amenorrhea (loss of regular menstrual cycle) and protein deficiency.
What is amenorrhea and protein deficiency and its effects?
- Female athletes, find it difficult to meet energy and nutrient needs while maintaining a low fat or body weight considered optimal for sports performance. Thus, they often restrict energy intake(EI) to make weight goals.
- Low EI, combined with high levels of exercise, increases the risk of developing exercise-related menstrual dysfunction (ExMD) and poor bone health.
- ExMD can be high in physically active women, ranging from 0% to 60%, and occurs across a continuum from mild disruptions in menses (no ovulation or luteal phase deficiency) to oligomenorrhea (cycles ≥ 35 day) and amenorrhea (no menses for >90 day.
- Low energy availability (EA) (i.e., energy remaining for body functions after exercise training) may lead to menstrual dysfunction through a leptin-controlled pathway.
- In ExMD, females have low leptin levels that contribute to the disruption of luteinizing hormone (LH) pulsatility via interference of gonadotropin-releasing hormone (GnRH) pulsatile.
- Sequentially, the ovaries decrease production of estrogen and progesterone, the hormones responsible for triggering the lining and egg of the uterus to be shed (menstruation) resulting in abnormal menses.
- Adequate dietary protein is important for supporting physiological adaptations to exercise, there is a growing need to determine the protein requirements for pre-menopausal
